What are two different ways to name a plane?

A plane can be regarded as a single letter, written in upper case and in cursive lettering, such as plane Q. It can also be named by identifying three points on the plane that do not form a straight line.

A plane is a flat surface that extends infinitely in all directions; thus, a lot of points can be found on a given plane. The plane can be named by taking any three points on it, in no specific order, as long as these points are not on a straight line. An example is plane ABC, given that points A, B and C are found on the plane and are not collinear.
